  1. 11. Pretreatmenteffect on induction time and polymorphic outcome of tolbutamide crystallizationin 1-propanol

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Georgios Chondrogiannis; [2017]
    Keywords : Crystallization; Nucleation; Polymorphism; Solution history; Pretreatment;

    Abstract : In this project, the effect of solution thermal and structural history on nucleation was investigated. Many researchers have shown that temperature and duration of pretreatment has an influence on induction time, polymorphic outcome and metastable zone width. READ MORE

  3. 12. Magma Storage of the Alkaline Tejeda Cone Sheet Swarm, Gran Canaria, Spain

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Max Jensen; [2016]
    Keywords : Gran Canaria; Tejeda cone sheet swarm; syenite; magma storage; thermobarometry; clinopyoxene; Gran Canaria; Tejeda inverterade kon-intrusioner; syenit; magma förvar; termobarometri; klinopyroxen;

    Abstract : Volcanoes with alkaline differentiated magma belong to the more explosive and destructive types, but knowledge about these systems is often limited. Unravelling the position and conditions in the source magma chamber systems that feed volcanism at the surface is vital to understand these systems better. READ MORE

  4. 13. Characterization of Succinate Producing Bacteria

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sofia Nyström; [2015]
    Keywords : xylose; succinic acid; chemical engineering; kemiteknik; biological production; Chemistry;

    Abstract : Målet med detta projekt var att studera två sorters bakterier, Actinobacillus succinogenes och Basfia succiniciproducens, och deras produktion av bärnstenssyra. Bärnstenssyra är en dikarboxylsyra som även är en metabolit i citronsyracykeln. READ MORE

  5. 14. Using Fe-Ti oxides and trace element analysis to determine crystallization sequence of an anorthosite-norite intrusion, Älgön SW Sweden.

    University essay from Lunds universitet/Geologiska institutionen

    Author : Sara Kullberg; [2015]
    Keywords : magma origin; AFC-model; ilmenite; ilmenite-rich leuconorite; anorthosite-norite; Earth and Environmental Sciences;

    Abstract : På Älgön, SV Sverige, finns en anortosit-norit intrusion tillhörande Hakefjordenkomplexet. Det finns dessutom två tillhörande enheter; en marginell monzonorit och en centralt belägen ilmenitberikad norit (IRL). I den ilmenitberikade noriten finns även olika sorters aggregat av Fe-Ti oxider. READ MORE

  6. 15. Basalt and Andesite Magma Storage and Evolution in Puyehue Volcano (40.5 °S), Chile

    University essay from

    Author : Joaquim Otero; [2013]
    Keywords : Volcano; Thermobarometry; Puyehue; Basalt; Andesite; Contamination;

    Abstract : The study of magmatic processes and their location in the crustal profile is fundamental for the understanding of the volcanic systems and their associated hazards. Changes and continuities in magma storage zones, fractional crystallization and crustal contamination are studied over a time span of 300 ka in Puyehue Volcano in the Southern Volcanic Zone, Chile.
